Jeep Wrangler eTorque Mild Hybrid Technology

What is Jeep Wrangler's eTorque Mild Hybrid Technology?

New for the 2019 Jeep Wrangler is an innovative eTorque Mild Hybrid system that is proven to improve fuel economy without sacrificing power, torque, or capability. It requires no additional effort by the driver and is part of both the 3.6L Pentastar V6 engine and the Turbocharged 2.0L I4 engine.

The new eTorque mild hybrid system is a replacement for the traditional alternator. It sports a belt-driven motor generator unit that executes several different functions.

How Does Jeep Wrangler's eTorque Mild Hybrid Technology Work?

A 48-volt battery pack works with the motor generator to create:

a seamless start/stop function;

a short-duration torque addition to the engine crankshaft in particular driving conditions; and,

brake energy regeneration to increase efficiency and responsiveness.

When the engine is running, eTorque's motor generator unit delivers 48-volt current to a 430 watt-hour lithium-ion Nickel Manganese Cobalt (NMC)-Graphite battery. The battery pack includes a 3-kilowatt DC-to-DC converter. This holds the battery's charge and converts 48 volts to 12 volts so that power can be use to power Jeep Wrangler's accessories and charge its conventional 12-volt lead-acid battery.

About the size of a small suitcase, the air-cooled battery pack is mounted to the interior rear wall of Jeep Wrangler's cabin. The battery pack's case is insulated to hush the noise generate by the dual cooling fans. Cooling air is then drawn from the vehicle interior and released through the built-in cabin exhausters.

Because of its greater efficiency in extreme temperatures, both the 3.6L Pentastar V6 engine and the Turbocharged 2.0L I4 engine with eTorque technology will keep a traditional 12-volt starter motor, which is ideal for cold starts and the initial start of the day.

Beyond spinning the engine for restarts, the eTorque also recaptures energy during deceleration and braking to recharge the battery pack. Further, eTorque also bolsters the driving experience of the 2019 Jeep Wrangler with additional torque to the crankshaft during gear changes, which minimizes noise, vibration, and harshness (NVH).

Both engines sport a liquid-cooled eTorque unit mounted on the front of the engine, which uses a pair of belt tensioners to ensure that the 8-rib drive belt stays tight when the unit is generating electricity or adding torque to the crankshaft.

Jeep Wrangler's eTorque Mild Hybrid Technology Warranty Information

The 2019 Jeep Wrangler comes backed by a 5-year/60,000-mile Powertrain Limited Warranty, which covers the cost of all parts and labor needed for repairing a covered powertrain component – engine, transmission and drive system. Additionally, it covers any necessary towing to the nearest Jeep dealer. For users who sell their Wranglers during the warranty period, the coverage is transferable to the new owner.

The standard three-year/50,000-mile Basic Limited Warranty delivers bumper-to-bumper coverage for the 2019 Jeep Wrangler, from the body to the electrical system.

In addition, as part of the Basic Limited Warranty, the Federal Emission Warranty covers the following parts of the eTorque system for 7 years/70,000 miles, whichever comes first.

EGR Cooler — 2.0L and 3.6L engines

Fuel Tank Assembly — 2.0L and 3.6L engines

Transmission Control Module — 2.0L and 3.6L engines

Turbocharger — 2.0L engine

Further, as part of the Basic Limited Warranty, the Federal Emission Warranty covers the following parts of the eTorque system for eight years/80,000 miles, whichever comes first.

The Warranty Coverage at A Glance graph in the 2018 Wrangler Standard Factory Warranty Booklet provides an overview perspective of the above described eTorque warranties on the Wrangler from 1 year/12,000 miles through 10 years/150,000 miles.

These components are not covered by any Mopar Vehicle Protection extended service warranty plan at the time of this publishing.
